VENTILATING-WINDOW-LOCKING DEVICE.

Application filed August 2, 1924. Serial No. 729,669.

To all whom it may con-0cm:

Be it known that I, BANNY GOLDSTEIN, a citizen of Rumania, residing at144 Varet Street, Brooklyn, in the county of Kings, city and State ofNew York, have in vented certain new and useful Improvements inVentilating-Window-Locking Devices, of which the following is aspecification.

My invention relates to a new and im proved form of ventilating windowlocking device.

One of the objects of my invention is to provide. a locking device whichcan be readily applied to any window, so as to securely lock said windowwhen it is partly open, so as to permit safe ventilation.

Another object of my invention is to provide a locking device which canbe readily removedand replaced without the necessity of removing anyfixed parts, manipulating keys, etc.

Another object of my invention is to provide a lockin device which willpermit the use of the ordinary window look, when the window is closed. I

Another object of my invention is to provide a locking device which canbe removed only at the inside of the window, and when the window isclosed.

Other objects of my invention will be set forth in the followingdescription and drawings, which illustrate a preferred embodimentthereof.

Fig. 1 is an elevation, partly in perspective, showing the inner side ofthe closed window.

Fig. 2 is a view similar to Fig. 1, showing the window partially open.

Fig. 3 is a section on the line 33, the locking member being shown inperspective.

The device is shown applied to a window of any ordinary type, having alower or inner sash hand an upper or outer sash 10. Y The sashes 10 andthe frame of the window above sash 11 have studs 15 and 14 rigidlyconnected thereto. The said studs are rigidly secured to metal basemembers which are rigidly connected by means of screws to the properparts. The window has the ordinary lock 12. i

A locking member or device is provided with a short upper slot 17 and along lower slot 16, through which the studs 15 and 14: can be caused toproject when the windowis closed, so that the shanks of saidstuds arefree to slide in saidgroove. The heads of said studs are longer than thewidths of said grooves so that the member 13 can be placed upon theshanks of the studs, and removed from the studs, only when the window isclosed, as shown in Fig. 1.

lVhen the upper sash locking device 13 turns on the shanks of the studs14: and 15, until the leg 18 rests upon the top of lower sash 11.

It is then impossible to further lower the upper sash 10, or to removethe locking device 13, because the heads of the studs 15 and 14 are nowinclined to their respective grooves 16 and 17. The parts are sodesigned that the upper sash cannot be lowered sufiiciently to enablethe entrance of any person.

Hence, ventilating and secure locking are simultaneously provided, sincethe member 13 cannot be removed until the window is closed, when themember 13 can be readily removed and replaced. According to myinvention, the locking member is so designed, that the upper part of thewindow cannot be lowered more than about six inches when it isheldagainst further downward movement.

10 is lowered, the- I have shown a preferred embodiment of I myinvention, but it is clear that numerous changes and omissions could bemade without departing from its spirit. 7

I claim:

1. A locking device for a window having upper and lower sashes slidablein a frame, comprising a first stud having a head and a shank secured tothe upper sash, a second like stud fixed to said frame above the top ofsaid lower sash, and a locking device having grooves through which theheads of said studs are adapted to project and in which the shanks ofsaid studs'are adapted to slidably fit, the lengths of the heads of saidstuds being greater than the widths of their respective grooves, saidlocking device being adapted to abut the top of said lower sash whensaid upper sash is lowered, to prevent further lowering of said uppersash.

2. A device according to claim 1, in which the said grooves are ofunequal length, and the first stud is adapted to project through theshorter groove.

3. A locking device for a window having upper and lower sashes slidablein a frame, sash When it is caused to move by the 10Wercomprisingprojecting members connected to ing of said upper sash, so as to preventfurthe upper slidable sash and to said frame, ther movementof said uppersash. V 10 and a locking member slidab'ly and turnabl y Intestimonywhereoi I hereunto affix my mounted on said projections the shape ofsignature.

said locking member being such that a portion thereof is adapted to abutsaid lower BANNY GOLDSTEIN.
